Sounds great

I really like the way these look and sound. Only problem I have had is it falling off the hangers when I hammer the throttle too often. Could have been an installation issue on my part, but also maybe not.

Great product. Install was a snap on my grand prix gxp. Engine and trans temp have went down. Great value.

Nice tone, affordable price

Sounds good, not too loud. Very reasonably priced compared to the flowmaster system for the GXP.

Great cat back besides...

This it a outstanding catback exhaust, sounds good, fits good and just overall a solid purchase. My only argument is that one of my stainless clamps doesn’t hold tight, could of been a lemon in a batch but it’s the only reason I won’t give a 5 star. Otherwise 10/10 recommend if you want a clean solid bolt on system.
